Lake County breaks down road-maintenance costs, equipment needs and materials

Lake County staff presented detailed figures for the costs and staffing needed to maintain the county's roads, saying equipment, material and haul distances drive widely different daily rates.

Michael (county staff member) said the county has about 200 lane miles of county gravel roads and outlined per-day equipment and staffing costs. "Equipment about $1,500, staff about $968," he said, adding that the county allocates roughly $622 per lane mile for certain gravel operations when mobilization and other overhead are included.

The presentation broke maintenance into work types with separate timelines and cost examples. Motor-grader and roller operations can move two to four miles a day on gravel; hauling road base from the county pit near the airport adds travel time, with one loaded truck able to haul roughly 65 cubic feet of road material. For chip seal projects, staff estimated an example cost of about $44,000 per day for a contractor-led job that lays roughly a mile and a half per day. A recent 10-mile chip-seal run cost about $197,000, the presenter said.

Pothole patching was described as a different scale: a crew with a truck and compactor can cost about $6,500 per day for cold-mix operations and temporary bagged supplies in winter months. Crack sealing and chip sealing commonly are contracted because they require larger crews and specialized equipment; the county estimated about 20 staff for a chip-seal operation and roughly 6,000 gallons of oil per project run.

Paving costs were highlighted as higher yet. Staff cited an example laid-asphalt price of about $165 per ton (including machine and rental equipment), with one recent small paving project reporting an asphalt material cost of roughly $80 for 32 tons in a day. Staff emphasized that that per-day amount does not capture all machine hours and support labor.

Equipment lifecycles and fleet accounting were also discussed. Staff noted some graders are 20-plus years old with as many as 19,000 hours, while the newest have about 1,000 hours. The county said it internally allocates replacement cost by tracking hourly use and effectively "leasing" equipment to departments for costing purposes; that accounting drives the $1,500 daily equipment figure.

The county emphasized that having its own pits and crushing capacity reduces haul distance and material costs compared with counties that must buy road base elsewhere. Michael said the county's pit near the airport provides crushed material but contains more clay in some sections, which affects bind with asphalt and long-term pavement performance.

The presentation concluded with staff noting that rising construction and equipment costs, coupled with constrained revenue, mean the county must prioritize which roads are rebuilt, overlaid or maintained with chip seal and to what extent in-house crews can perform the work versus contracting it out.

Ending: County staff presented these numbers as planning inputs for the coming construction season; no formal budget action was taken during the work session.
